if you start it from console what do you have?

I also have this problem with Ubuntu 18.04.4 LTS and the error message is:
"$ xnview
/opt/XnView/XnView: error while loading shared libraries: libopenal.so.1: cannot open shared object file: No such file or directory"

I don't know if this dependency is inherent to xnview.
Thanks

you need to install openal
